wheels E, E, E, E and E journal Patented June-2, 190s;

each other by the cross-arms C of the holdersjC each of which is referably in the form p of a double hook, as p ainly shown in Fi .9.

By the arrangement described the articles are freely hung on the holders between the chains so that the articles can "be readil engaged by brushes and other devices as ereinafter more fully described.

The endless carrier D passes over s rocket on the main frame A and on the shaft of the sprocket wheels E and between the latter is arranged a drum E so that the articles in passing over the drum E drop off the holders 0 and down into a boxF held on the frame A. The up- I' run of the endless carrier D while passing cm the sprocket wheel E to the sprocket wheel E, travels at its side edges in lo tudinal side guideways G. attached to die main frame A, so that the 11 per run of the endless carrier D is held in horizontal position, and the articles while carried forward by this upper run are subjected-t0 the cleaning action of revoluble yieldingly mounted brushes H, H, H H and Hi, of which the '80 brush H is' arranged above the upper run of the endless carrier D and operates in conj'unction with a cushion or a spring resistance plate spring I, supportedfrom one. of the guideways G. As shown in the drawings, '85

the brush-H revolves directlyabove the u per" run of the endless carrier D, while t e resistance plate I is located immediately below the sald upper run of the endless carrier D. Thus as the article isacarried along it '99 asses between the resistance late I and the rush H, and is then acted on y the bristles of the brush to remove extraneous matter from the article. The rotar brushes H H form a ,air of horizontally 'sp'osed brushes, and are ocated on oppositesides of the up r run of the endless carrier D, so that all si d s of the article are acted on by the bristles of the said brushes while passed between'the same. The brushes H and H are likewise arranged as a pair, respectively located above and below the 11 per run of the endless carrier D, so that tile article is carried between the said air of brushes to be acted on by the bristles t ereof at thetop and bottom. Each 5 of the rotary brushes H H H and H isof the same construction, that is, provided with a shaft H (see Figs. 4 and 5) on which are secured flanges H, screwing on the ends of a tubular hub H, on which are. held vdisksfi extraneous matter from the articles under The said disks H are rovided treatment. with pins H", engaging apertures 12 in the adjacent disks H and the end disks H located adjacent to the inner faces of the flanges H, are without radial grooves, but are provided with pins H for engaging the corresponding apertures H in the next following disk H. After the disks and their bunches of bristles are assembled on the hub H ,-the flan es H are screwed on to the ends of the tubu ar hub H and press against the outermost disks H so as to securely clamp the several disks in position between the flan es H, and then the flanges are fastened in p ace on the shaftH by set screws. By havin the flanges H, the articles are readily passe between the flanges so as to be engaged operator, or the said shaft is y the free ends of the bristles, to allow the latter to eflectively act on the articles with a view to properly clean the same. By having the grooves H scribed, it is evident that a large number of bunches of bristles H may be used to insure thorough cleaning of each part of the surface of the article under treatment.

In order to singe hairs or the like, suitable burners or singers J, J J and J are provided, extendin close to the ath of the article carried a ong by the en ess carrier D, one of the burners J being preferably located in the rear of the brush H above the brushes H and H the burners J and J being located at a point between the sprocket wheels E, E and the burner J being preferably located adjacent to the sprocket wheel E Water supply ipes are arranged over the path of the artic e, to readily wash off loosened matter.

In order to impart the necessary rotary motion to the brushes H, H, H H and H as well as to the endless carrier D, the following arrangement is made. On the main frame A is journaled a longitudinally extending shaft K, provided at one end with a crank arm K adapted to be turned by the provided with suitable pulleys connected with other machmer for imparting a rotary motion to the:

shaft by power. The shaft K drives two additional longitudinal shafts K K likewise journaled in bearings on the main frame having its arranged in the manner de-- A, and for this purpose a sprocket chain L is em loyed, passing over sprocket wheels L, L 34? and L, of which the sprocket wheel L is secured on the shaft K, the sprocket wheel L is attached to the shaft K the sprocket wheel L is secured to the shaft K and the sprocket wheel L is an idler. Now, when the shaft K is rotated a simultaneous rotary motion is given to the shafts K and K On the shaft K is secured a bevel gear wheel N (see Fig. 1) in mesh with bevel gear wheel N fastened to the shaft .H of the rotary brush H, so that when the machine is in operation the rotary brush H is rotated from the sh aft K by the bevel gear wheels N and N. On the shaft K is secured a bevel gear wheel N in mesh with a bevel gear wheel N 3 secured onthe upper end of the shaft H for the rotary brush H, and a bevel gear wheel N, secured on the shaft K is in mesh with a bevel gearwheel N attached to the upper end of the shaft H for the ,rotary brush H so that both brushes H and H are rotated in unison. A bevel gear wheel N 6 is secured to the shaft K and is in mesh with a bevel gear wheel N secured to the transverse shaft H of the rotary brush H and on the shaft K is secured a bevelgear wheel N in mesh with a bevel gear wheel N secured on the shaft H of the rotary brush H; thus the brushes H and H are'rotated in unison with each other "and in unison with the other brushes H and H As previously stated the revoluble brushes H, H, H H and H are yieldinglymounted and for this urpose the shaft H of each brush has its evel gear wheel end j ournaled in a bearing H mounted toswin on the shaft from which the brush sha t H is driven. Thus the bearing H for the shaft H of the brush H is hung on the shaft K on which is also hung the bearing H for the shaft H of the brush H and on the shaftK are hung the bearings H for shafts H of the brushes H, and H The bearing H for the shaft H of the brush H is hung on the shaft K. The free end of each shaft H is mounted to turn in and to slide in a bearing H (see Fig. 10) attached to the main frame A. The shafts H for the brushes'H, H and H are each pressed on by a spring H to swing the corresponding brush H, H and H towards the endless carrier D and the articles supported thereon by the use of the holders 0, it being understood that the brushes H and H require no springs as these brushes, by their own weight, move downward in contact with the articles to be cleaned.

On the shaft K is secured a worm 0 (see Figs. 1 and 2) in mesh with a worm wheel 0 fastened on a transversely extending shaft 0 journaled in suitable bearings attached to the main frame A. On the shaft 0 is secured a gear wheel 0 in mesh with a pinion O secured to the shaft E carrying the sprocket wheel E, so that when the shaft K is rotated a slow rotary motion is transmitted by the worm O and worm wheel 0 to the shaft 0 and the rotary motion of the latter is'transmitted by the gear wheel 0 and the pinion O to the shaft E and the sprocket wheel E, so that the latter imparts a traveling motion to the endless carrier D in the direction of the arrows a, indicated in Fig. 2. Suitable hoods P are provided for the rotary brushes H, H, H and H On the shafts for the sprocket Wheels E, E is mounted a guard Q to allow the holders C to butt against, while the operator places the.

article onto the holders.

When the machine is in operation, the operator standing at the front end of the machine takes a pigs foot or other article at a time from one of the boxes B and places it upon the holder C which travels u ward over the sprocket Wheel E, and this ho der slowly carries the pigs foot, first, between the brush H and the resistance plate I, then between the pairs of brushes H and H", H and H so that the brushes brush the top, bottom and sides as well as the ends, and the article is also subjected during its forward travel to a singeing process by the flames of the burners J, J, J 2 and J When the cleaned article is carried by the endless carrier D over the sprocket wheels E then the articles drop off the holder C and fall down into the box F from which the cleaned articles can be removed.

Although I have shown and described a number of brushes sufficient for properly cleaning pigs feet and the like, the number of brushes may be increased if found necessary.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. In a cleaning machine, an endless traveling carrier, holders on the said carrier, a revoluble brush above the carrier for engaging the articles held on the said holders, a cushioned resistance late below the carrier opposite the said brus the holders and their articles passing between the brush and the resistance plate, and pairs of revoluble brushes in the rear of the said sin le brush and its resistance plate, one pair 0 brushes being mounted on vertical pivots and the.
